Cancellation and replacement of PUSCH

Abstract

Apparatuses, systems, and methods for cancellation and/or replacement of PUSCHs. A user equipment device (UE) may configure a first PUSCH and a second PUSCH, where the first PUSCH may correspond to a configured grant and where the second PUSCH may correspond to a configured grant or scheduled by a PDCCH on a serving cell. The UE may determine that at least one transmission occasion associated with the first PUSCH overlaps in time with at least one transmission occasion associated with the second PUSCH. The UE may drop transmissions scheduled for the second PUSCH, e.g., based on determining that a priority of the first PUSCH is higher than a priority of the second PUSCH, e.g., starting with a first symbol of a repetition of the second PUSCH which overlaps in time with one or more repetitions of the first PUSCH.

What is claimed is: 
     
       1. A method for selection of physical uplink shared channels (PUSCHs), comprising:
 configuring a first PUSCH and a second PUSCH, wherein the first PUSCH corresponds to a first configured grant, and wherein the second PUSCH is scheduled by a physical downlink control channel (PDCCH) on a serving cell; 
 determining that at least one transmission repetition associated with the first PUSCH overlaps in time with at least one transmission repetition associated with the second PUSCH; and 
 dropping one or more transmission repetitions, wherein the dropping includes:
 determining whether a downlink hybrid automatic repeat request (HARQ) process identifier (HPID) of the first PUSCH is different from an HPID of the second PUSCH; 
 in response to determining that the HPID of the first PUSCH is different from the HPID of the second PUSCH, dropping, when a priority of the first PUSCH is higher than a priority of the second PUSCH, for each respective repetition of the second PUSCH, transmission repetitions scheduled for the second PUSCH starting with a first symbol of the respective repetition of the second PUSCH which overlaps in time with one or more repetitions of the first PUSCH; and 
 in response to determining that the HPID of the first PUSCH is not different from the HPID of the second PUSCH, dropping transmission repetitions scheduled for the first PUSCH starting from a first symbol of a repetition of the first PUSCH which overlaps in time with one or more repetition of the second PUSCH.
